Great Piece
This is a must have if your bike is still in stock form. You can definitely feel the additional power, and it has a very nice exhaust note. I would definitely buy again.

easy to install
This was our first purchase from DK and we are impressed by the ease in on-line ordering and all the reference ratings on-line. It was easy to be sure we were ordering the right part for our bike. It was easy to install the pipe (a 12 year old did it) and it sounds great!

Good performance Sound Price
Instructions are good. Very quick fit and install. Improved acceleration. Sounds good. It does not appear that the S/A is removable as it's a spiral style that is internal.
